1975-76
Tom Presley was hired as the Product Manager (also involved in marketing) to begin MPC project. John Karpowitz was then hired to design & build Modular Powered Circuits (MPC) modules. In 1976 The MPC guitars debut.
1978
  • Outlaw MPC & Outlaw MPC Bass (both named after the band 'The Outlaws' who were Electra endorsers at the time), Semi-Acoustic MPC (ES-335 style), X910 'Derringer' MPC (Explorer) all debut. Gibson style headstocks are also changed this year to the more familiar wave or fan shaped ones most MPC fans are used to.
  • 1979-80
  • The Contoured Ultima MPC Les Paul, Vulcan MPC (a Les Paul copy with a Tele curve on upper bout), Leslie West MPC (sort of a Les Paul Special) all debut in this time frame.
  • 1981-84
    Ties with Matsumoku are further solidified in 1981 and decision made to merge SLM Electra brand with Matsumoku's Westone brand. At some point in the early 80's, some production is moved to Korea. MPC Ultima X960 debuts in 1981. In the fall of 1983, Electra brand becomes Electra-Phoenix. By early 1984 it became Electra-Westone and by the end of 1984 it is just Westone.
    St. Louis Music Inc's reason to abandon the Electra line were; overall, the MPC were not a great marketing success (seems unbelievable with the success Electra's are now enjoying :-)
    1985-NOW
  • Electra Westone became Crate which is still around.
  • Dating your Electra: Matsumoku made guitars have serial number in which the first one or two digits represent the year of manufacture. A guitar with a serial number that begins in '0' or '80' would have been built in 1980 (this is just a guideline and DOES NOT apply to all Electra models but seems a safe bet for 1977-1981 guitars).
    The Electra MPC's claim to fame was, and is, on-board effects (more commonly referred to as effects modules). No stomp boxes required. If you want to use an effect (wah, phase shifter, etc) , all you have to do is flip a switch on the front of the guitar, and turn a knob (also on the front of the guitar) to adjust the intensity of the effect. Twelve different modules were available in all.

    Over the years major musicians endorsed the MPC line, such as, Peter Frampton, Leslie West (signature model), ELO, Allen 'Free Bird' Collins, Chris Squire (MPC Bass), The Outlaws (signature guitar & bass), and Rick Derringer (X910 model is also known as the 'Derringer' model). Despite these endorsements, the Electra line still disappeared while the SLM went on to produce Westone & Crate products. Today, SLM distributes Crate, Ampeg, Alvarez & Austin products. So as you can see, it's a misconception that SLM disappeared or went bankrupt...they just changed.
    The first school of thought was that the Electra MPC line were shoddily manufactured gimmick guitars. Now, twenty five plus years later, they are finally starting to be recognized for superior craftsmanship and playability. For years many Electra's languished in pawn shops while buyers focused on vintage Fenders and Gibson's. Now, there seems to be a resurgence in both their value and reputation for quality.
